A closed circuit television (CCTV) is a video magnification system consisting of a video screen interfaced with a video camera. Factories, office buildings, hotels, educational institutions and the like typically employ closed circuit television monitoring systems for surveillance and security purposes. A closed circuit television CCTV is a supervisory system for observation of different locations from a central supervisory station. systems are typically comprised of a closed circuit television network having a plurality of television cameras each arranged to view a particular location. Closed circuit television systems ordinarily include a control or console panel and monitor mounted remote from a television camera from which a television picture is received. At the central supervisory station there're a monitor for receiving video signals from the individual television cameras, a controlling device or operating device for controlling the operation and functions of the television cameras, and a switching circuit for selecting one of the television cameras to be connected to the controlling device and the monitor. Cables extending from the video cameras are terminated with a BNC jack connector and the back panel input connectors are BNC socket connectors each receiving one of the cable jack connectors. The operation and functions of each television camera is controlled by a control signal supplied from a controlling device and each television camera transmits video signals to the central supervisory station. Remote control of the camera is achieved via camera control devices such as lens focus, iris, zoom, and camera attitude mechanisms mounted on the camera. Closed circuit television system provides high contrast, inverse video display, gray scale, false colors, natural colors, and control of contrast level and brightness.
